Just get the connectors, and a length of cable, and make your own. It's really
not at all difficult. The trickiest part is pressing the two parts of the
connector
together (and it ain't that tricky). A vise would work fine, or, what I use,
one of those wooden clamps--you know, with the two big screws... you
might have seen them in highschool woodshop.
Anyway, I can't get to my Pulsar right now, but if the contacts are standard
0.1" spacing... well, here's the following part numbers from the Digi-Key
catalog:
Part# Price Mfg. part#
MCE20K-ND 4.62 3461-001
MCE20G-ND 1.26 89520-0041
Those are both 3M parts. The first uses gold plated beryllium copper contacts,
the second uses phospher bronze.
CCE20G-ND 3.22 (10 for 24.44)
CCE20T-ND 2.73 (10 for 20.68)
These two are made by CW Industries. The first has gold contacts, the second,
tin.
All four of these are just standard 20 contact card edge connectors with IDC
contacts. (strain reliefs are also available, but probably not necessary for
this
application.) Personally, I think I'd opt for the gold contact material, and
I've
never used the CW Industries products, so...
Then, there's the following ribbon cable:
MC20G-X-ND 3.95 / 5 ft 7.33 / 10 ft 16.36 / 25 ft
(replace the 'X' in the part number with the number of feet desired. eg. 5 , 10
, 25 ....)
It's just plain ol' gray flat ribbon cable, 20 conductors, 28AWG, 7x36 tinned
stranded copper. (the 7 x 36 means there are 7 strands of 36AWG in each
conductor. 'AWG' means American Wire Guage, if anybody's wondering.)
The prices are USD.
They also have color coded cable, if that trips your trigger...
Use a nice sharp pair of scissors, or something like a utility knife and a
steel ruler to cut the cable to length. Press the connectors onto the cable,
and you're in business. The IDC contacts will automatically make the
connections, so... don't try to strip the wires. (in other words, do _not_
strip the wires.) When you position the connector, try to get it at a
half decent right angle to the cable. Begin applying pressure with
whatever tool you're using, and continue until the two parts meet. Just
examine the connector, you'll figure it out...
Often times I'll press the connector on first, then carefully trim the excess
cable off with a _sharp_ blade, using a couple of passes. There are, of
course, tools available for attaching these connectors, but those kinds of
specialty items are, quite often, somewhat on the pricey side.
I've made these, *plenty* of times for hard drives... lot's of stuff, and
they've never failed to work.
Oh, and Daevid, the folks at Digi-Key usually tend not to be complete morons,
but if ya called 'em up trying to use Pulsar speak, or something like
that--yeah,
it's very likely they had no idea what you were talking about.
Anyway,I've
dealt with them repeatedly over quite a few years. They've always struck me
as being very good at what they do (and they package their parts very well,
and all that crap...) Just... thought I'd mention that.
Good luck!
Jeff
